The piston burning loss of diesel generator is one of the common faults in use. What are the main reasons for the piston burning loss of diesel generator? Here ricoda generator set manufacturers for you to explain!
1. If the injector drops oil or atomizes poorly, the fuel in the diesel generator will be burned at the top of the piston for a long time, resulting in high temperature at the top of the piston, thus causing the piston to burn out.
2. The piston of diesel generator is seriously worn or cracked. The engine oil runs up, causing the piston to burn.
3. The choice of inferior lubricating oil accelerates the wear of the cylinder of the diesel engine, increases the exhaust pressure of the crankcase, and increases the carbon deposition in the combustion chamber, resulting in the burning of the piston.
4. The fuel supply quantity and time of each cylinder of the diesel engine are uneven, which worsens the combustion process of some cylinders and forms carbon deposit. The heat of diesel combustion causes the piston top temperature in some cylinders to be too high, which causes the material of the diesel engine to melt due to thermal fatigue and causes the piston to burn out.
5. The quality of piston cylinder liner is not good enough. If the piston of diesel engine is cast with porosity, porosity, micro-cracks, slag inclusion and other defects, these defects will become a fatigue source under the action of high temperature and high pressure, resulting in the fatigue damage of the piston; The slag in the piston first melts, causing the piston to melt.
6. The piston top clearance is not proper. If the piston top clearance is not properly adjusted when assembling the diesel engine, the compression ratio of the diesel engine will be affected and the live sierra cylinder or piston will be burned out.
